Over the past decade, Vancouver psych-rock five-piece Black Mountain have honed their spacey aesthetic, growing into a slick, groovy vibe machine and pumping their epic records full of gorgeous vocal harmonies, Hawkwind-­style synth soundscapes, Jon Lord-­flavored organ madness, David Gilmour guitar wizardry, and stoner-rock stomp. It’s a sort of heavy metal for the masses, relying on a massive wall of guitar as much as it does a sunny pop sensibility. But Black Mountain didn’t always sound so festival ready: on their self-titled 2005 debut, they were a sleazy, desert-fried psych-metal outfit, toying with gigantic, evil riffs and bombastic Sabbath drums. Their style was loose, weird, and reckless, and they played it like the brand-new band they were—with tons of bite and nothing to lose. This tour is in support of the tenth-anniversary reissue of that first album: this time Black Mountain (Jagjaguwar) comes out on a two-LP set at the end of June. The new deluxe edition doubles the album’s length by adding early recordings, demos, and live cuts from the group in their scuzzy infancy. —Luca CimarustiBlack Mountain also plays at Do-Division Street Fest on 5/29.
